The first attempt to translate Wonder Woman to the small screen occurred in 1967. The success of the Batman television series led Batman producer William Dozier to commission a pilot script by Stan Hart and Larry Siegel. Batman writer Stanley Ralph Ross was then asked to perform a re-write, after Hart and Siegel's script was deemed unsuitable. A portion of the pilot, under five minutes in length, was filmed under the title Who's Afraid of Diana Prince? The piece starred Ellie Wood Walker (Robert Walker Jr.'s wife) as Diana Prince, Linda Harrison as Diana's "Wonder Woman" alter ego and Maudie Prickett as Diana's mother.
This pilot episode was never broadcast and the project was taken no further. The pilot has been circulated on the Internet and is of interest to Planet of the Apes fans for the early appearance of Linda Harrison, who would later go on to play Nova in the first two films of that series.
